Introduction

I recently needed to apply CORS (Cross Origin Request Scripting) to a project that I'm working on. If found 2 posts that helped to achieve it:

• Max Walker's post at Empire Windrush blog
• James Ward's SaleForce Proxy OSS project

I combined both to solve my problem: I have a User CRUD (Play!) webservice and a (Play!) web app that services a SPA (Single Page Application). The SPA needs to access the CRUD webservice, but to acheive this, I would need to apply some CORS rules on both applications.

  val someValue: Int = ??? /* public, immutable */
  var someVariable: Long = ??? /* public, mutable */
